摘要
针对车载高炮射击时车体姿态对射击精度的影响问题,提出了一种基于刚柔耦合模型修正火炮射击诸元的方法。以某车载高炮为研究对象,通过建立其刚柔耦合模型对车体姿态进行预测,火控系统将获取的射击方向上的车体姿态响应实时分解到沿车头方向和垂直于车头方向,经过纵、横倾及车向反变换后由载车不稳定坐标系转换为载车地理系下,再经滤波与解相遇问题求解得到地理系下的目标诸元,随后将地理系下的目标诸元通过纵、横倾及车向变换后得到载车不稳定系下的火炮射击诸元,从而将修正后的瞄准诸元提供给火炮。为验证修正方法的可行性与适用性,以另一型车载炮为对象进行了试验验证,试验结果表明:经诸元修正后的火炮射击精度得到明显改善,火炮射击初期高低和方位弹丸脱靶量均值分别减小了53.1%和41.3%,修正效果显著,研究可为车载高炮火控射击诸元修正提供一种新思路。
Aiming at the influence of vehicle body attitude on the shooting accuracy of vehicle-mounted antiaircraft gun,a method based on rigid-flexible coupling model was proposed to modify the firing parameters of the gun.Taking a vehicle-mounted antiaircraft gun as the research object,the rigid-flexible coupling model was established to predict the vehicle body attitude.The fire control system decomposed the acquired vehicle body attitude response in the firing direction into the direction along the front and the direction perpendicular to the front in real time.After longitudinal,heeling and vehicle-reverse transformation,the vehicle unstable coordinate system was converted into the vehicle-borne terrain system.Then the target elements under the geographical system are transformed by longitudinal,heeling and vehicle-direction to obtain the gun firing elements under the unstable system of the vehicle,and the modified aiming elements are provided to the gun.In order to verify the feasibility and applicability of the modified method,another type of vehicle mounted gun was tested.The test results show that:After the modification,the firing accuracy of the gun is obviously improved,and the mean miss distance of the altitude and azimuth projectile in the initial firing of the gun is reduced by 53.1%and 41.3%,respectively.The correction effect is remarkable,and the research can provide a new idea for the fire control firing of the vehicle-mounted anti-aircraft gun.
